I notice with DF 9.7 that when I run Microsoft Teams on a secondary monitor (visible, not minimized), the Alt-Tab list on the primary monitor includes "Microsoft Teams Notification" window of class "Chrome_WidgetWin_1".

The notification is not visible at the time I'm doing Alt-Tab

I have Alt-Tab configured to "Show on current monitor only, show current windows only".

I see mention in the Advanced Settings of an alt-tab blacklist... how can we add to it?
